"The Internet of Money Volume Two: a collection of talks" is the spectacular sequel to the cult classic and best seller "The Internet of Money Volume One: a collection of talks" by Andreas M. Antonopoulos. Volume Two contains 11 more of his most inspiring and thought-provoking talks, including: Introduction to Bitcoin; Blockchain vs Bullshit; Fake News, Fake Money; Currency Wars; Bubble Boy and the Sewer Rat; Rocket Science and Ethereum's Killer App; and many more. Volume Two also includes an all-new frequently asked questions section!In 2013, Andreas M. Antonopoulos started publicly speaking about bitcoin and quickly became one of the world's most sought-after speakers in the industry. To date, he has delivered more than 75, TED-style talks in venues ranging from the Henry Ford Museum in the United States to packed-out Bitcoin Meetups around the world including Brazil, the Czech Republic, and New Zealand, and every talk is completely different.In these performances, Antonopoulos walks onto the stage and delivers a live, unscripted talk. Without a deck in sight, he unleashes his latest insights into the lightning-fast changes surrounding bitcoin. Combining the knowledge of one of the world's leading blockchain technologists, with cultural context, comedy, and the flair of a performance artist, Antonopoulos conveys an up-to-the-second understanding of bitcoin to live audiences worldwide.Many of these talks were so visionary, their content so educational, that they were curated and refined into a book form. On 7 September 2016, The Internet of Money Volume One was launched on The Joe Rogan Experience podcast (the interview has since been viewed more than 300,000 times). With its genesis in the lived, human experience, The Internet of Moneyoffered something that was desperately needed: an explanation of the philosophy, economics, politics, poetics, and technologies of bitcoin and open blockchains set within a broad historical context and using clear, simple language that delighted general audiences and bitcoin enthusiasts alike. During its first year, Volume One quickly became a hit in the global crypto-currency community-appealing to audiences from fields as diverse as the arts, sciences, and humanities. As one reader wrote: "It provides a uniquely accessible take on a mind-bendingly abstract system." The Internet of Money Volume Two: a collection of talks builds on that momentum and offers readers an opportunity to experience more these inspiring and thought-provoking talks in print. It also includes a bonus question and answer section, where Andreas answers some of the most frequently asked questions from audience members during his worldwide tour. Volume Two is a sequel that rivals, even exceeds, the first, in content, scope, and vision. These talks are intellectual fire-starters you won't want to miss. Make this book part of your collection and see why Andreas M. Antonopoulos is considered the most powerful and engaging voice in crypto-currency and blockchain.

While many books explain the how of bitcoin, The Internet of Money delves into the why of bitcoin. Acclaimed information-security expert and author of Mastering Bitcoin, Andreas M. Antonopoulos examines and contextualizes the significance of bitcoin through a series of essays spanning the exhilarating maturation of this technology. Bitcoin, a technological breakthrough quietly introduced to the world in 2008, is transforming much more than finance. Bitcoin is disrupting antiquated industries to bring financial independence to billions worldwide. In this book, Andreas explains why bitcoin is a financial and technological evolution with potential far exceeding the label "digital currency." Andreas goes beyond exploring the technical functioning of the bitcoin network by illuminating bitcoin's philosophical, social, and historical implications. As the internet has essentially transformed how people around the world interact and has permanently impacted our lives in ways we never could have imagined, bitcoin--the internet of money--is fundamentally changing our approach to solving social, political, and economic problems through decentralized technology.
